当远程连接到webpack-dev-server时，我得到一个“无效的主机头”消息

我正在使用Cloud9作为一个环境。io ubuntu虚拟机在线IDE和我已经减少了这个错误，只是运行应用程序与Webpack开发服务器。

我用:

webpack-dev-server -d --watch --history-api-fallback --host $IP --port $PORT

$IP是一个包含主机地址的变量 $PORT包含端口号。

当在Cloud 9中部署应用程序时，我被指示使用这些变量，因为它们有默认的IP和PORT信息。

服务器启动并编译代码，没有问题，但它没有显示索引文件。只有一个空白屏幕与“无效的主机标题”作为文本。

这是请求:

这是webpack.config.js:

        // see webpack 1 upgrade guide
      },

        }
      }
    ]
  },

    compress: true
  }
}

Webpack开发服务器返回这个，因为我的主机设置。在webpack-dev-server/lib/Server.js第60行。从https://github.com/webpack/webpack-dev-server

我的问题是我如何设置正确通过这个检查。任何帮助都将不胜感激。

当前回答

因为我用npm start启动服务器，我需要改变包。Json格式如下:

"scripts": {
  "start": "webpack-dev-server --progress --disableHostCheck"
},

vue-cli用户注意事项:

将vue.config.js文件放在根目录下，使用相同的代码行:

module.exports = {
  configureWebpack: {
    devServer: {
      public: '0.0.0.0:8080',
      host: '0.0.0.0',
      disableHostCheck: true,
    }
  }
};

与其编辑webpack配置文件，更简单的禁用主机检查的方法是通过添加一个.env文件到你的根文件夹，并放入:

DANGEROUSLY_DISABLE_HOST_CHECK=true

顾名思义，禁用它是不安全的，建议只在开发环境中使用。

在包中。json，在“脚本”，添加参数——disableHostCheck=true 如:

"scripts": {
        "start": "ng serve --host=0.0.0.0 --configuration=dev --disableHostCheck=true"
}

我使用nginx运行在docker容器内部，根据url路由流量。

在nginx配置文件中添加以下两行代码，为我修复了“无效主机头”的错误。参见下面的配置文件(default.conf)。

proxy_set_header Host            $http_host;
proxy_set_header X-Forwarded-For $remote_addr;

首先，下面是我简单的两行Dockerfile来创建nginx容器，然后用路由配置它。

FROM nginx
COPY ./default.conf /etc/nginx/conf.d/default.conf

因此，当构建映像时，default.conf文件被复制到nginx容器内的配置目录。

接下来，default.conf文件如下所示。

upstream ui {
    # The ui service below is a ui app running inside of a container. Inside of the container, the ui app is listening on port 3000. 
    server ui:3000;
}

upstream node-app {
    # The node-app service below is a server app running inside of a container. Inside of the container, the server is listening on port 8080. 
    server node-app:8080;
}

server {
    listen 80;

    location / {
        # The root path, with is '/' will routed to ui.
        proxy_pass http://ui;

        ################## HERE IS THE FIX ##################
        # Adding the following two lines of code finally made the error "Invalid Host header" go away.

        # The following two headers will pass the client ip address to the upstream server
        # See upstream ui at the very begining of this file.

        proxy_set_header Host            $http_host;
        proxy_set_header X-Forwarded-For $remote_addr;      
    }


    location /api {
        # Requests that have '/api' in the path are rounted to the express server.
        proxy_pass http://node-app;
    }
}
#

最后，如果你想看一下我的docker compose文件，它有所有的服务(包括nginx)，在这里

version: '3'
services:
  # This is the nginx service. 
  proxy:
    build:
      # The proxy folder will have the Dockerfile and the default.conf file I mentioned above. 
      context: ./proxy 
    ports:
      - 7081:80

  redis-server:
    image: 'redis'

  node-app:
    restart: on-failure
    build: 
      context: ./globoappserver
    ports:
      - "9080:8080"     
    container_name: api-server

  ui:
    build:
      context: ./globo-react-app-ui
    environment:
        - CHOKIDAR_USEPOLLING=true      
    ports:
      - "7000:3000"
    stdin_open: true 
    volumes:
      - ./globo-react-app-ui:/usr/app

  postgres:
    image: postgres
    volumes:
      - postgres:/var/lib/postgresql/data
      - ./init-database.sql:/docker-entrypoint-initdb.d/init-database.sql
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=password

volumes:
  postgres:

我通过在nginx配置中添加主机头的代理来解决这个问题，就像这样:

server {
    listen 80;
    server_name     localhost:3000;

    location / {
        proxy_pass http://myservice:8080/;

        proxy_set_header HOST $host;
        proxy_set_header Referer $http_referer;
    }
}

我补充说:

proxy_set_header主机

$http_referer;
